Hollow glass microspheres are often used as a filler material in extruded and injection molded plastics to improve their mechanical properties and reduce their weight. Here are some ways in which hollow glass microspheres can be used in these applications:
Improved mechanical properties: Hollow glass microspheres can improve the mechanical properties of extruded and injection molded plastics by increasing their stiffness, strength, and impact resistance. The addition of hollow glass microspheres can also reduce the amount of shrinkage and warpage that occurs during the cooling process.
Reduced weight: The use of hollow glass microspheres as a filler material can reduce the weight of extruded and injection molded plastics, making them more lightweight and easier to handle. This is particularly important in applications where weight is a critical factor, such as in the automotive and aerospace industries.
Improved dimensional stability: The addition of hollow glass microspheres can improve the dimensional stability of extruded and injection molded plastics by reducing their coefficient of thermal expansion. This can help to reduce the amount of distortion that occurs during temperature changes and can improve the accuracy of the final product.
Improved surface finish: Hollow glass microspheres can also improve the surface finish of extruded and injection molded plastics by reducing the amount of surface defects and improving their surface smoothness.
Improved electrical properties: Hollow glass microspheres can improve the electrical properties of extruded and injection molded plastics by increasing their dielectric strength and reducing their dielectric constant. This can be particularly important in applications where electrical insulation is required, such as in the electronics industry.
